Patent EP-0479611-A1 (EP)
Inventor: SJOESTROEM HAEKAN
IPC: C08F8/00
Filed: 1991-10-04
Abstract: In the invention was prepared a crosslinkable ethene (co)polymer by copolymerizing first with ethene an unsaturated monomer containing a first hetero group to an ethene (co)polymer having said first hetero group and then by grafting to the obtained ethene (co)polymer a crosslinking agent having an unsaturated crosslinking group and a second hetero group reacting with said first hetero group. Typical reacting hetero group pairs are hydroxyl and carboxyl groups. By the method ethene (co)polymers are obtained, which are easily crosslinkable and have excellent properties.

Abstract: A lever (6) pushes, by means of a roller (59), a ring (S1) to the bottom of a groove (G1) of the piston head (P). Rollers (94) and (95) carried by a reference lever (12) and a measurement lever (13) bear respectively on the piston head and on a projecting portion of the ring (S1) which is pushed by the roller (59). Means (22, 23, 38, 44) transmit the magnitude of the detected projection to a measurement sensor (100). A motor (82) causes the rollers (59, 94, 95) to rotate about the piston in order to enable measurements of the projections of the ring over one revolution to be taken. The measurements are compared with predetermined allowed ranges in order to sort the pistons as a function of the correction (adjustment) or of the non-correction (non adjustment) of the assembly of the rings which they carry and of the geometry of the latter. <IMAGE>

Abstract: Process for obtaining semiordered polyamideimides. 
<??>More particularly, it consists in carrying out the polycondensation in two separate stages: 
 
  1) reaction between a proportion of an aromatic diisocyanate and all of the trimellic anhydride in the presence of dimethylalkyleneurea of pH </= 7 until the intermediate compound is dissolved, 
  2) successive addition of one or more aromatic diacids and of the remainder of the aromatic diisocyanate to the dimethylalkyleneurea of pH </= 7 until the polyamideimide obtained is completely dissolved. 
 
<??>The semiordered polymers thus obtained have a Tg lower than the random polymers, and this makes them easier to form.

Title: Fluid treatment apparatus.
Inventor: HAYES JOHN
IPC: B01J19/08
Filed: 1991-10-07
Abstract: An apparatus for magnetically treating fluids such as water and hydrocarbon fuels; in the case of water to increase the solubility of salts and reduce scale or soften any deposits which are formed, and in the case of hydrocarbons to increase fuel combustion efficiency. The apparatus improves on existing techniques by including first and second magnetisation means mounted on a fluid-carrying non-metallic pipe, the first generating a constant magnetic field in the fluid and the second generating an alternating magnetic field in the fluid, and superimposed on the constant field. The simultaneous use of alternating and constant fields enhances the aforementioned effects as compared with a constant field alone. The frequency of the alterning field is varied to obtain the optimum results.

Abstract: A weighing apparatus for determining the weight of a load while the load is in vertical motion, comprising a stationary support, a lifter for lifting and lowering the load thorough a range of vertical motion, and at least three elongate weigh beams secured to the stationary support and the lifter by respective opposite ends thereof and rigidly spacing the lifter horizontally from the stationary support. The weigh beams sense the weight of the load continuously while the load is in motion. A computer is operatively connected to the weigh beams for receiving and processing weight information sensed by the weigh beams and outputing data representative of the weight of the load. A first weight is sensed representing the container and refuse contained in the container. A second weight is sensing after the container has been emptied and subtracted from the first weight to derive a net weight representing the weight of the emptied refuse. The lifter includes a reader for reading data from an identity tag carried by refuse containers to be emptied.

Abstract: A phase-shifting lithographic mask (500) is made by a procedure involving only a single patterned electron, ion, or photon bombardment of a positive resist layer. The bombardment is arranged to produce three regions (14, 15, 16) in the resist containing mutually different bombardment doses (D1, D2, 0)per unit area, one of which is typically zero. These three regions are then used--in conjunction with separate wet development steps with two developers of different concentrations--in order to pattern the resist layer and to form an underlying double layer consisting of a patterned opaque layer ( 13) located on a differently patterned transparent phase-shifting layer (12), the transparent phase-shifting layer being located on, or being part of, a transparent substrate (11). (With suitable geometrical rearrangement of the regions, a negative resist layer can also be used.)

Abstract: In the prior art, selective epitaxial growth (SEG) of semiconductors, performed typically in rectangular windows penetrating through a masking layer located on a major surface of semiconductor substrate, suffers from unwanted facet formation at the corners of the windows--whereby the desirable planar area available for transistor fabrication is reduced. Such facet formation is suppressed--i.e., the area occupied by unwanted facets is reduced--by adding a relatively small lobe penetrating through the masking layer at each corner of each window prior to performing the SEG, whereby transistor packing density can be increased.

Abstract: A paper feed system for an image reproduction machine, representatively a printer, has a shelf member (44) disposed within the machine housing and rotatably carrying a turntable (76) on its upper side. Two transversely oriented pairs of diametrically opposite upper and lower paper trays (136,138;100,102) are removably supported on the turntable, with portions of the upper trays overlying the lower trays. The turntable may be rotated to vertically interpose a selected one of the four trays between a stationary picker roller (36) and a lifter structure (140) positioned beneath the picker roller. The lifter structure has a portion which moves upwardly through a shelf opening, and a turntable opening aligned therewith, to engage the selected tray and lift it toward the picker roller to bring a paper stack held in the tray into engagement with the picker roller which operates to successively remove sheets from the stack and deliver them to the machine's paper feed path. The lifter structure may then be lowered to return the selected tray to its initial position on the turntable and permit another tray to be selected for rotation into a position from which it may be lifted to the picker roller. When a lower tray is selected, a shift mechanism (122-126) is operated to move the upper trays out of the lift path of the selected lower tray. The trays may be accessed by operating a drive motor (54) which drives the turntable shelf horizontally outwardly through a housing side wall access opening.
